Watched your video about nunu and tried out the item list you had listed and i liked it, Nunu is one of my favorite person on LoL and just wanted to say thanxz for the tips with him.

I'd go for runes other than crit damage, since abilities in general can't crit. I'd try magic pen/magic resist instead.

You might also want to check if the effects from Warden's and Frozen Mallet stack. They might, I don't know.

You have so little magic resist it's not funny. Try a magic resist tanking item instead of having so much armor.

yes i know how crazy nunu's speed goes w/ the blood boil that iill keep that in mind and possibly try a game w it...thx for the positive feedback

Wow that's pretty cool. I like your masteries too. I would still go ghost instead of teleport because it makes you insanely fast w/ blood boil. (This could allow you to get to towers as well)
